Microscale Hogwarts Express

Many important scenes take place aboard the Hogwarts Express in the Harry Potter movies and books. The train is in almost every book and movie and is the place where Harry meets Ron and Hermione for the first time and makes an enemy of Draco.

My MOC is a microscale Hogwarts Express crossing a bridge between two mountains over top of a treed valley.

I wanted to make the number 20 as hidden and naturally part of the build as possible so I put it as part of the bridge connecting the mountains. The number 20 can be seen highlighted in the second picture.
